TEMPORARY BINDER.

Specification of Letters Patent.

Patented. Oct. 24, 1905.

A plication filed November 17, 1904. Serial No. 233,106.

To a. whom it may concern:

Be it known that I, GEORGE H. Moons, of Brookline,'in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Temporary Binders, of which the following is aspecification.

This invention has for its object to provide a temporary binder adaptedparticularly to confine a pack of paper memorandum-sheets, which areprovided with perforations near one edge to receive the sheet-engagingmembers of the binder, the device as a whole being adapted particularlyfor use in schools, &c.

The invention has for its object to provide a simple, inexpensive, andconveniently-operated temporary binder the sheet-engaging members ofwhich shall be wholly within the covers of the binder.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a plan view of a temporary binder embodying myinvention. Fig. 2 represents a section, on a larger scale, on line 2 2of Fig. 1. Fig. 3 represents a side view of one of the perforated papersheets. Fig. 4 represents a perspective view of a modification.

The same reference characters indicate the same parts in all thefigures,

In the drawings, 0 represents a base or back to which are hinged orflexibly connected suitable side pieces or covers 716, the whole formingan inclosure adapted to cover one edge and both sides of a pack of papersheets. To the back a is movably connected a sheetconlining hook 0,adapted to enter a perforation (1' in a paper sheet (Z. In the preferredembodiment of my invention (shownin Figs. 1 and 2) the hook c iscomposed ofwire and is one of two similar hooks formed by bending theend portions of a single length of wire, the central portion 0 of saidlength being left straight and confined in two bearings or sockets c e,which are affixed to the back a. Said sockets may be formed by bendingflexible pieces of thin sheet metal and securing the end portions ofsaid strips by means of eyelets or rivets a, as shown in Fig. 2. Thecentral portion 0 of the wire is adapted to turn in the bearings e, andthe outer portions of the hooks c are therefore adapted to swing towardand from the back (0. Then the hooks are swung outwardly from the back,as shown by dotted lines in Fig. 2, they are in position to convenientlyreceive or discharge the sheets (Z. When the outer ends of the hooks aremoved downwardly toward the back, as shown by full lines in Fig. 2, theyare in position to confine the sheets. The back is provided with meansfor detachably securing the outer ends of the hooks c in the positionshown by full lines in Fig. 2, the said means, as shown in Figs. 1 and2, comprising detents ff, each of which is a coil of wire formed at theend portions of a length of wiref. The wire is so coiled as to formtapering throats f f, the wider portions or months of which face eachother and are adapted to receive the outer end portions of the hooks cc, the said end portions being provided with notches c, which engage thewire portion, which forms one side of the throatf' as indicated in Fig.2. The hooks c are resilient and are adapted to be sprung inwardlytoward each other to enable their outer portions to enter the throats\Vhen the hooks are released, their outer portions are caused by theresiliency of the wire to spring into the throats f and thus cause theinterlocking of the outer ends of the hooks with the throats in themanner shown in Fig. 2. The hooks are thus locked or wedged in place andprevented from swinging outwardly. The coiled portions of the wireforming the detentsf may be secured to the back (a by any suitablemeans, such as by eyelets or rivets g.

In Fig. 4 I show a modification in which wire hooks c are employed,these hooks being formed on resilient arms 0", which are integral witharms 0 on which wire detents c are formed, said detents being similar tothe detents f above described and secured to the back (0 by rivets 0 Theparts 0 and 0" are connected by a curved neck 0, through which passes arivet 0, engaged with the back a. The hooks 0 have notches in theirouter ends similar to those in the hooks c. WVhen the hooks c aredisengaged from the detents c, the resilience of the arms 0" causes thehooks to spring outwardly, as shown by dotted lines in Fig. 4, so thattheir outer portions are separated from the back to permit the insertionor removal of the sheets.

It is to be noted that the detents f or 0 each comprise two members orjaws, one of which engages the notched face of the end of the hook c andthe other serving as a backing against the opposite face of said end tohold the notched face in engagement with the first-mentioned IIO memberor jaw. The notched ends of the hooks when in engagement with theircooperating detents are wedged between the two members or jaws of thedetents, and therefore are not likely to be accidentally sprung out oflocked position. It will furthermore be noticed that the two members ofeach detent at the point where they are engagedby the ends of the hooks0 are separated slightly. This, in connection with the rounded uppersurfaces of the wire of which the detents are made, enables the ends ofthe hooks to be snapped into engaging and locked position, from whichthey can be readily displaced only by lateral movement of the two bookends in opposite directions.

It will be seen that either of the embodiments of my invention abovedescribed constitutes a simple and efi'ective binder the parts of whichare entirely closed between the back and the covers and are adapted tobe conveniently manipulated to release and confine the paper sheets.

I claim 1. A temporary binder comprising a back, a sheet-confining hookmovably connected at one end with the back, and a yielding detent fordetachably securing the other end of the hook to the back, said detentand hook being formed to permit the hook to be snapped'to lockingposition.

2. A temporary binder comprising a back, a hook movably connected at oneend with the back, and a detent attached to the back and adapted todetachably engage the other end of the hook, said detent having twomembers or jaws between which the end "of the hook may be wedged.

3. A temporary binder comprising a back, a plurality of hooks eachmovably connected at one end with the back, and a plurality of detentsattached to the back and adapted to detachably engage the other ends ofthe hooks, said detent having an engaging member and a backing member tohold the parts in engagement.

4. A temporary binder comprising a back,

a resilient hook movably connected at one end with the back, and adetent attached to the back and having a tapered throat adapted toengage and wedge the other end of the hook.

5. A temporary binder comprising a back, a resilient hook movablyconnected at one end with the back and having a notch at its other end,and a detent attached to the back and having a tapered throat, one sideof which is adapted to engage the notch of the hook, while the otherside of said throat bears against the rear of the hook to hold itsnotched face against the first-mentioned side of the throat.

6. A temporary binder comprising a back, a resilient wire hook movablyconnected at one end with the back and having a notch at its other end,and a coiled wire detent attached to the back and having a taperedthroat, the notched end of the wire being adapted to be laterally wedgedin said throat.

7. A temporary binder comprising a back, a length of wire having astraight central portion, and end portions formed as resilient hooks,bearings for said central portion affixed to the back, and detentssecured to the back and adapted to engage the outer end portions of saidhooks, each of said detents comprising two jaw members adapted toreceive a hook end wedged between them.

8. A temporary binder comprising a back, a length of wire having astraight central portion, and end portions formed as resilient hooks,bearings for said central portion affixed to the back, and anotherlength of wire having coiled end portions attached to the back, said endportions forming tapered throats adapted to engage the outer endportions of the hooks.

In testimony whereof I have affixed :my signature in presence of twowitnesses.
